The solution suggested by mahenkj2 is the way to achieve this. Possibly the reason you are seeing an outline of the 'Print' button is because it last had the focus.
HOWEVER, as Trevor G asked, why do you have buttons on a report? Access basics 101; Tables store your data, Forms allow you to record data, Reports show you what is stored. If you are printing a 'form' as a report you just need to replicate the appearance as a report (without the buttons) and print the report FROM the form.
